The origin of graphic design critic Helfand's book on every type of circular interface originates in her own extensive collection of these ubiquitous objects. Sandwiched between the lengthy introductory and concluding essays is a catalog with color plates, dimensions, manufacturer, and descriptive entry of the "movable, concentrically-aligned" wheels that allow you to dial for information of all sorts, including dial-a-weight, dial-a-word, dial-a- remedy, and dial-a-recipe.

I was so happy to find this book in my university library. I love volvelles, wheel charts, etc. I do not own any, but I am constantly on the lookout for them. There was one I saw at a gift shop in Rehoboth Beach,Delaware. The name of it was something like: [Wheel Chart] of Lost Things -- you could spin it around and get some clues to where you might find something you lost. I stood in front of it for a long time, thinking, I should buy this ... but there was a part me that convinced me that I didn't NEED it ... I regret listening to that part.
A fascinating look into the world of volvelles, or information wheels, through the ages. Anyone interested in charts, tables, information formatting, and arcane design through the ages needs this book.
